3 15-year-old Elero roller shutter switch with Cosmic program and sunlight replace probe had lately, as they increasingly showed deficits in their functions. Reset and reprogram caused only temporary success. Since the total price of the above switch combination of both brands is approximately the same price and I had already received from the dealer a Somfy switch, I decided for another Somfy switch, which I then even installed and programmed. With a little amateur electrical knowledge to install went smoothly. The conn. Programming with the help of a quite detailed user then worked successfully after several failed attempts. Quite simply, it is only when one has made it several times! Somewhat confusing is the variety of functions of the switch (for roller shutters or blinds, Cosmic / hard times, Eu / US etc. Recommendation: First, all the things that do not emphasize eligible the opposite the old switch the programming, however, is much simpler and the function of the sun light sensor is pleasant. While the old Elero switch to solar activation the roller shutter curtain in relatively short time intervals repeated short up and then possibly down went again, this eliminates the Somfy switch totally. However, I have now the sun light sensor for the desired tank position slightly fasten deeper on the disk, so that it is now becoming exposed to the sun, but this of course is not a real problem! It can be but also set up a tank position, which I did not try. This light sensor also can be attributed to different light intensities to adjust what the old did not work. The model shown has a gray-white appearance and can also be supplied with other frames. Similarly, there is the sun sensor with different cable lengths, which may play a role may vary depending window size. Standard are probably 2 m. The Somfy sun sensor I think priced however exaggerated! But whichever course of Gesamtsetpreis! I will stay definitely also for the rest of Austauch Elero switch in this Somfy Model.
